title: Extensive pharyngeal hemorrhage induced by dipyridamole.
abstract: An extensive hemorrhage in the pharynx appeared in association with dipyridamole administration to a diabetic patient. The hemorrhage caused dysphagia and subsided when the drug was discontinued. Coagulation tests were normal except for a decreased platelet aggregation. Platelet factor 3 and the aggregation tests with adenosine diphosphate and epinephrine were abnormal during the hemorrhagic event and returned to normal after discontinuation of the drug.
